For a single unit like the Gamma 601, I’m with the buy once, cry once crowd.
Uptime is king. I’d rather have a rock-solid 500 GH/s running for 2 years straight than a 1.4 TH/s unit that crashes every week because it’s pushing the thermal limits.
If you use the
legendary KPT-8 thermal paste, you'll have problems.
GD2 thermal paste will give you excellent results. You might want to try it to avoid paying more. Sometimes people buy a car that costs $10,000 and put in it the same expensive oil that is used in cars that cost $500,000.
